Method for automatic controlling a fraction of inspired oxygen of medical ventilator

摘要

The present invention relates to an automatic control method of inhaled oxygen concentration in a respirator, which controls inhaled oxygen concentration (FiO2) automatically depending on the situation by comparing target blood oxygen saturation and inhaled oxygen saturation (SpO2) measured in a patient within a range of the inhaled oxygen concentration (FiO2) prescribed by a doctor. In particular, the present invention relates to an automatic control method of inhaled oxygen concentration in a respirator, which automatically determines FiO2 from a biosignal measured from the patient, thereby having clinical advantages.
